[Tested] Catalyst 11.1a Hotfix (Jan26): Gains up to 18% in OpenGL Tessellation (TessMark)
I just finished to test the new Catalyst 11.1a hotfix (January 26 2011!!!) to verify the gains in OpenGL tessellation claimed by AMD HERE. My friends, this new hotfix (you can download it here) brings some nice improvements in TessMark, especially in Moderate and Normal tessellation levels (moderate: X8, normal: X16, extreme: X32 and insane: X64).
TessMark settings: 1920×1080 fullscreen, no AA, no PostFX, map set 1.
Scores with Cat 11.1a Jan26 and the last WHQL Cat 10.12:
Catalyst 11.1a Hotfix Jan26_2011:
- Moderate: 31562 points (526 FPS): +14.9%
- Normal: 9781 points (163 FPS): +18.86%
- Extreme: 2201 points (37 FPS): +3.7%
- Insane: 541 points (9 FPS): +0.37%
- Moderate: 27469 points (458 FPS)
- Normal: 8229 points (137 FPS)
- Extreme: 2122 points (35 FPS)
- Insane: 539 points (9 FPS)
More scores are available here: SAPPHIRE Radeon HD 6970 OpenGL performances.
I did the test with a freshly compiled version of TessMark (I will release it this week) because I noticed some crashes with the current TessMark 0.2.2 and Catalyst hotfix.
I also tested the OpenGL tessellation with Unigine Heaven 2.1.
Settings: 1920×1080 fullscreen, OpenGL rendering, tessellation: normal, shaders: high, AA: 4X, 16X anisotropic filtering.
- 24.7 FPS, Scores: 622
Catalyst 11.1a hotfix Jan26:
- 25.9 FPS, Scores: 654: +5%
And here is the DX11 score with the same settings and Cat 11.1a hotfix:
- 42.0 FPS, Scores: 1057
There is still an important bottleneck somewhere in AMD’s OpenGL driver…
